Combining trees

Up till now you could choose from the following 3 trees/databases when searching for persons, namely:1. the main database 'MISJPOGE-DRENTHE'2. the database 'Zaligman-Dwinger', and3. the database 'COHEN'

After a long process of combining and removing doubles finally the first two trees were combined, which means that in the future the choice still only concerns:- the main database 'MISJPOGE-DRENTHE', and- the separate database for 'COHEN'
